DYEINGr-MACHINE.

Patented Oct. 25, 1921.

Application filed November 23, 1918. Serial No. 263,856.

To all whom it may concern Be it known that 1, JAMES H. THOMPSON, a citizen of the United States, and a resident of Trenton, county of Mercer, State of New Jersey, have invented certain Improvements in Dyeing-Machines, of which the followin is a specification.

My invention relates to certain 1mprove ments in dyeing machines, particularly of the type in which the hanks of yarn are suspended in a vat and in which a circulatlng means is located at one end of the vat so that the liquor will be circulated through the vat in either direction.

The invention is also applicable to machines for dyeing loose stock, such as raw cotton, raw wool, rags, &c. In this instance, a cage is used instead of'the means for suspending the hanks of yarn 1n the vat.

The object of my invention is to improve the construction of this type of machine and to provide a solid end with reduced passages in which the circulating means is located so as to make the circulation more positive.

In the accompanying drawings:

Fig. 9 is a sectional view on the line 9-9, F 2; l

1 is the vat havingsides 2 and an end 3.

- At the opposite end is a circulating device and the housing for this circulating device consists of two heavy wooden pieces 4; and 5. The piece 4 .in the. present instance, forms the end of the vat, while the piece 5 stops short of the top and bottom so as to allow the liquid to circulate over the top and under the bottom. In these two end pieces are vertical cylindrical passages 6,

three, in the present instance, one-half of each passage being formed in the end section a and the other half in the. section 5. They are of substantially the same diameter as'the circulating propellers 7, which are mounted on vertical shafts 8 adapted to bearings 9 on the frame 10 mounted on the upper portion of the machine.

In the present instance, I have shown three circulating passages 6 and three circulating propellers 7, each propeller being mounted on a shaft 8, and on the frame 10 is a. power driven shaft 11 having bevel wheels 12 and 13 arranged to mesh with beveled wheels 14 on the ends of the shaft 8. This power shaft has, in the present instance, a sprocket wheel 15 around which a drive chain passes. The power shaft can be shifted longitudinally by a lever 16 pivoted to the frame, and by throwing the lever in one direction the bevel gear wheels 12 will mesh with thegears it 011 the propeller shafts, and by moving the shaft in the opposite direction the bevel wheels 13 will mesh with the bevel wheels 14 on the power shaft to change the direction of the flow of liquor; Thus the direction of the flow of the liquor can be quickly changed by merely moving the lever.

In order to heat the liquor in the vat, I provide two steam pipes 17, one extending on each side of the vat at or near the bottom thereof, as shown in F igs.-2 and 3. Each pipe 17 is connected to a vertical pipe 18 forations increase in diameter from the point where they communicate with the pipe 18 to the opposite end of the vat so as to distribute the steam through the vat more evenly. The perforations are also placed closer together at the forward end than at the inner end for the same purpose.

Located at the bottom of the vat directly below the passages 6 is a wooden plank 21, Figs. 4: and 5, on which are three projecting pieces I 22, preferably arranged in radial lines from the center of each passage. This arrangement is for the purpose of breaking up any currents which may be formed in the liquor as it is discharged from the bottom of the passage into the tank, insuring the distribution of the liquor more evenly throughout the vat, as the liquor has a tend. ency to run in channels, causing, in some colors, a streaking of the liquor which they secure the two parts of the side bars together and clamp the ends of the cross bars, Fig. 9. The cross bars are preferably on a line with the lower edge of the piece 5 and form a bottom channel through which the liquor can flow freely to and from the circulating passages.

26 is the supporting frame for the hanks of yarn and this frame consists, in the present instance, of two longitudinal side beams 27 and a central beam 28. These beams are connected together by cross beams 29,

provided with eyes 30, which are engaged by the lifting tackle when it is desired to lift the frame with the hanks of yarn thereon into or out of position on the vat. There is a series of perforations 31, which extend through the side beams and there is a series of perforations 32 in the central beam 28 which do not extend through the beam, as clearly shown in Figs. 3 and 8, and the yarn sticks 33 are located in these perforations, one series of'bars being on one side of the center beam and the others being on the opposite side. By providing the central beam,

as shown, the sticks need not be so long as usual, and, consequently, they do not sag and become accidentally detached from the supporting frame and are not warped out of position. Furthermore, they carry a less number of hanks than heretofore and they are more readily handled by'the operator than where long sticks are used.

Directly above the yarn carrying sticks there is a grating similar to that at the bottom of the vat, consisting of a series of wooden bars 34. These bars arespaced a given distance apart and are clamped onto the beams 27 and 28 by bars 35. These cross bars 34 are short, one set extending from one side beam to the center beam and the other from the center beam to the other side beam. They do not extend through these side beams or the center beam. They rest in sockets formed in the bars so that, when it is desired to replace one of the bars on account of breakage, all that is necessary is to loosen one of the side clamping bars sufficiently to remove the broken cross bar and to place a new one in its stead. V

Carried by the supporting frame is a cover 36'for closing the vat during the process of dyeing and this cover has two hinged portions, one at each end, so that access can be readily had to the'interior of the vat to inspect the circulation. The remainder of the cover is made of a series of sections, which can be removed, if found desirable.

The operation of the machine is as follows :-The dye liquor is placed in the vat and the circulating means is set in motion so as to circulate the liquor in the vat and steam is added to it in order'to bring it to the proper temperature. The particular color of dye is also added until it is thoroughly incorporated with the dye liquor. The hanks of yarn are then placed on the sticks and the sticks are located in the frame,

'which is supported from an overhead trolley, or beam, and, when the liquor is in the proper condition to dye the material, the yarn frame is swung over the vat and lowered into it so that the hanks of yarn will be submerged in the liquor.

I preferably locate on each inner wall of the vat longitudinal bars 38 which come in close contact with the side beams for the supporting frames of the yarn and close the space between the side beams and the side of the vat so as to prevent the circulation of liquor at this point and to insure all of the liquor being circulated through'th'e hanks of yarn. If the circulating means is moving so as to cause a downward current in the vat the liquor is caused to flow up through the passage 6 and over the yarn, flowlng down through the space between the hanks of yarn to the bottom and returning. After this is continued for a certain length of time, the direction of movement is reversed by shifting the lever 16, when the liquor will flow up through the hanks of yarn in the vat and down through the passage 6. This reversal of the liquor causes all parts of the yarn to be thoroughly dyed and prevents uneven dyeing at the sticks.

' Vhile the piece 4 forms, in many instances,

one end of the vat, the piece 5, which stops short of the top and bottom of the vat, forms what may be termed a weir over and under which the liquor circulates. It will be noticed that the circulating propellers are located near the upper end of the passages and there is no supporting means for the propellers below the liquor in the vat,

consequently, as the'supporting means for the shaft is in the overhead structure and as the passages are cylindrical, there is no need of bearings in the passages. By this means the apparatus can be readily'assembled.

When loose stock is being dyed, such as raw cotton, raw wool, rags, &c., I dispense with the stick-supporting frames and mount, in the vat, a cage of any suitable form through which the dye liquor can circulate. This cage can be lowered at one side of the vat and can be transferred to the vat in the same manner as the frame for circulating the hanks of yarn.

While I have described the yarn supporting means and the gratings in this application, they are claimed in an application filed by me on the 20th day of August, 1921, Serial No. 493,852.

I claim:

1. The combination in a dyeing machine, of a vat having a solid structure at one end with vertical cylindrical passages of an even diameter throughout and rotating circulating propellers of substantially the same size as the passages and mounted therein.

2. The combination in a dyeing machine, of a vat having a solid structure at one end consisting of two pieces, each having semicylindrical passages therein so that when the two pieces are arranged together they form cylindrical passages, one piece forming the end of the vat and the other piece stopping short of the top and bottom of the vat and forming a weir; circulating propellers mounted in the passages; and means for driving the propellers.

3. The combination in a dyeing machine, of a vat having an end structure made in two pieces and having vertical circulating passages therein, means in the circulating passages for causing the circulation of liquor therein; a perforated longitudinal steam pipe located at each side of the vat, near the bottom, connections of said steam pipes extending upward between the two pieces of the end structure, and attached to a supply ipe.

P 1-. The combination in a dyeing machine, of a vat; a circualating passage at one end of the vat; means for circulating the liquor in the vat and through the passage; and deflecting bars at the base of the passage to break up any currents which may form in the liquor flowing out into the vat from the passage.

5. The combination in a dyeing machine, of a vat having a circulating passage at one end, said passage being formed by two pieces, one of said pieces forming the end of the vat and the other piece forming a weir; a plank in the bottom of the vat under the weir; and a series of radiating projections on the plank for breaking up any currents which may form in the liquid flowing into the vat from the passage.

In witness whereof I afiix my signature.

JAMES H. THOMPSON.
